GOVERNOR CONTROL.

Application len December 3, 191?.

of Illinois, have invented certain new andv useful YImprovements inGovernor Controls, of which the following is a specification.

My invention relates to Y. governors particularly internal combustionengines.-`

An object of the inventionis to combined manual and governor controlledfuel feeding mechanism so arranged that manual control throughout theentire range provide `of fuel feeding is possible but inA which itis-impossible for the operator to fail to perform any steps which wouldhave the effect of operatively disconnecting the engine fromv itsgovernor contr-f.-l whenthc manual control is released. This is animportantpoint. IIt is common to adjust the governor in such manner thatthe exigirle will run at a certain predetermined speed but it frequentlybecomes necessary, momentarily, to decrease or increase suchpredetermined speed, l am aware that in the constructions heretofortlproposed it has been possible to so disconnect the governor from thethrottle or speed regulating means that this may be accomplished.However, there in such constructions the danger that the operator mayneglect. to reestablish the governor oontrol and the engine may beinjured and great. damage done by racing. To avoid this difficulty andassure governor control irrespective of the volition of the. operator, lhave provided an extremely simple mechanism so arranged that the manualcontrol of the fuel valve may be effected throughout.- its entire rangebut which will automatically be re-connected when the manual control isreleased.

The invention will be more stood b v reference drawings, wherein,

Figure l an elevation of a construction such as contemplated b v me,the'governor being shown diagrannnatically,

Fig. Q is a view taken at right angles to that of Fig. l. and

Fig. 3 is a fragmentary detail, the view being taken on thel line 3*3 ofFig. 2.

and adapted .for rotation to increase 'or lessen the amount of fuelsupplied by means of the reciprocating rod l2. The rod is suitablyconnected tothe upper end of a lever or crank Vt3, which ismounted'forfreedonl of rotation on a shaft l-l, The crank is providedwith a projection or handle l5, at

ionel side and a pin l0, at the other side.

- portion 20, and

rlhe governor, indicated diagrannnatically at 17. may be of any approvedtype. The fly-ball governor shown is vadapted'to engage one arm 18, of abell-crank, also mounted on the shaft ll, the other arm 19, of thebell-crank being provided at its upper end with a hook formed partly bythe curved partly by the leaf-spring 2l. The hook thus formed is adaptedto resiliently engage the pin 16. It will be noted that the rigidportion 20, abuts and lies at one. side of the pin 16, that is, in such.manner that the fuel valve yrod l2, is positively moved toward areduced speed position. Yi'hen the rod is to be moved in the oppositedirection the engagement is effec-ted by the frictional contact of theleaf-spring with the pin. In operation the bell-crank or equivalentstructure, is oscillated by the vertical reciprocation of the governorunder the action of the fly-balls.

By means of the handle or knob l5, the operator may disengage the fuelcontrol members .from the governor lever to secure speeds lower thanthat fixed by the governor. If he wishes to secure higher speeds he mustdo so by overcoming the force exerted by the governor. In whateverposition the fuel control lever is placed by the operator, it will beengaged by the governor lever upon any increase in speed of the engine.lf the operator leaves the two levers in disengaged position and thespeed of the engine should increase, the governor lever will move up toand engage the pin 16, of the manual control lever and thereafter thecontrol will be effected solely by the governor.

The manner of mounting the levers is nnimportant. It is only necessaryvthat'the path or are of nieve-ment of the manual con-f trol and governorlevers should .intersect in order that it be impossible for the operatorto dis-engage the governor and prevent its control at higher speeds thanthose determined by the governor setting.
